Description

Technical Field

[0001] The utility model relates to an antenna installation device, in particular to a mounting frame connecting a vehicle-mounted antenna and a lifting rod, belonging to the technical field of vehicle-mounted communication equipment accessories. Background Art

[0002] The vehicle-mounted cabin / compartment cabin is a special compartment equipment that can be loaded and unloaded or fixed on a special vehicle. It is used in different fields such as field geological exploration, communication engineering, radio and television, water conservancy engineering, construction engineering, combat command, etc. The antenna of the communication vehicle is often supported by a lifting rod. When the antenna is in use, the lifting rod drives the antenna to rise out of the cabin roof to improve the sensitivity of the antenna; when the antenna is not in use, the lifting rod drives the antenna down into the cabin, which is very convenient to use. Usually the antenna is installed at the center of the lifting rod. In order to reduce costs and reduce installation space, several antennas need to be installed on one lifting rod. At this time, it is necessary to add an antenna mounting bracket. Utility Model Content

[0003] The utility model aims to provide a vehicle-mounted antenna mounting frame which has a simple structure and can be used for synchronously lifting and lowering two antennas.

[0004] The utility model is realized through the following technical solutions:

[0005] A vehicle-mounted antenna mounting bracket, wherein the lower middle side of a horizontally arranged vehicle-mounted antenna mounting bracket is fixed on the top end of a vertically arranged lifting rod, the vehicle-mounted antenna mounting bracket comprises an antenna bracket and a counterweight bracket fixedly connected into one body, the antenna bracket comprises an integrated upper horizontal rod, a connecting oblique rod and a lower horizontal rod, the antenna mounting tube is vertically welded and fixed on one end of the upper horizontal rod and one end of the lower horizontal rod respectively; the counterweight bracket comprises an integrated upper platform, an oblique connecting rod and a lower vertical rod, one end of the upper horizontal rod is welded to one end of the adjacent upper platform, and the counterweight block is fixed on the lower end of the lower vertical rod.

[0006] The purpose of the utility model can be further achieved by the following technical measures.

[0007] Furthermore, the cross-sections of the antenna bracket and the counterweight bracket are both groove-shaped.

[0008] Furthermore, the middle portion of the upper horizontal rod is fixed on the top end of a vertically arranged lifting rod, and the lifting rod is close to the antenna mounting tube on one end of the upper horizontal rod and away from the antenna mounting tube on one end of the lower horizontal rod.

[0009] Furthermore, a counterweight block in the shape of an annulus is fixed on the lower end of the lower vertical rod.

[0010] Furthermore, triangular rib plates are welded respectively at the upper horizontal rod, the concave connection between the diagonal rod and the lower horizontal rod, and the concave connection between the diagonal connecting rod and the lower vertical rod.

[0011] Furthermore, a plurality of lightening holes are provided at intervals in the longitudinal direction of the antenna bracket and the counterweight bracket.

[0012] The utility model adopts an antenna that is vertically supported on both ends of the antenna bracket, and the top end of the lifting rod is asymmetrically supported between the two antennas of the antenna bracket. The moment on both sides of the lifting rod is balanced through the counterweight block at the lower end of the counterweight bracket, so that the lifting rod is evenly stressed and the antenna is lifted and lowered smoothly, which significantly improves the safety and reliability of the antenna lifting, extends the service life of the lifting rod, and reduces the use cost of the utility model.

[0013] Advantages and features of the present invention will be illustrated and explained by the following non-limiting description of preferred embodiments, which are given as examples only with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 3 yes Figure 1 Top view of the . DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1 and Figure 2 As shown, the vehicle-mounted antenna mounting bracket of the utility model is horizontally arranged, and includes an antenna bracket 1 and a counterweight bracket 2 fixedly connected into one body, the antenna bracket 1 includes an integrated upper horizontal rod 11, a connecting oblique rod 12 and a lower horizontal rod 13, and the antenna mounting tube 3 is vertically welded and fixed to the right end of the upper horizontal rod 11 and the left end of the lower horizontal rod 13. The middle part of the upper horizontal rod 11 is fixed to the top of the vertically arranged lifting rod 10 by four fixing screws 111. Due to the location requirements of the installation of the antenna 20, the lifting rod 10 is close to the antenna mounting tube 3 on the right end of the upper horizontal rod 11 and away from the antenna mounting tube 3 on the left end of the lower horizontal rod 13, resulting in the support member at the top of the lifting rod 10 being in an unbalanced state, and the counterweight bracket 2 is required to balance the antenna bracket 1 and the antenna 20 thereon. Prevent the antenna 20 from becoming unstable and tipping over.

[0019] In order to reduce the eccentric moment of the antenna bracket 1, Figure 3 As shown, the weight of the antenna bracket 1 on the side away from the lifting rod 10 gradually decreases to reduce the influence of the moment generated by the eccentricity on the performance of the lifting rod 10.

[0020] The counterweight bracket 2 includes an integrated upper platform 21, an oblique connecting rod 22 and a lower vertical rod 23. The right end of the upper horizontal rod 11 is welded to the left end of the adjacent upper platform 21, and the counterweight block 24 is fixed to the lower end of the lower vertical rod 23. Figure 2 As shown, the counterweight 24 of this embodiment is annular, and the size of the counterweight 24 can be changed according to the eccentric position to balance the torque on both sides of the lifting rod 10. The counterweight 24 located at the lower end of the lower vertical rod 23 lowers the center of gravity of the utility model, making the utility model and the antennas 20 on both ends of the utility model and the lifting more stable.

[0021] The cross sections of the antenna bracket 1 and the counterweight bracket 2 are both groove-shaped, which improves the strength and rigidity of the utility model and prevents deformation and failure.

[0022] In order to improve the rigidity of the utility model and prevent plastic deformation, triangular ribs 14 are welded at the concave connection between the upper horizontal rod 11, the connecting diagonal rod 12 and the lower horizontal rod 13, and the concave connection between the diagonal connecting rod 22 and the lower vertical rod 23. In order to reduce the weight of the utility model, a plurality of lightening holes 112 are respectively provided at intervals in the longitudinal direction of the antenna bracket 1 and the counterweight bracket 2.

[0023] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
